Prediction

Tom thinks his next book, 'A Future Worth Creating', will be shorter than 'The Pentagon's New Map'. His editor thinks it'll be 100k words.

I predict it'll be as long or longer than PNM. Tom has a lot to say.

Question: would it be worthwhile to explore some, in this book or another (or some other forum) what the things are that could derail this vision? If Great Power War isn't a danger anymore, what is?
